詳細介紹

產品介紹：

The Planetary Ball Mill PM 100 CM is a powerful benchtop model with a single grinding station and an easy-to-use counterweight which compensates masses up to 8 kg. It allows for grinding up to 220 ml sample material per batch.

The extremely high centrifugal forces of Planetary Ball Mills result in very high pulverization energy and therefore short grinding times.

The PM 100 CM operates in centrifugal mode which leads to a more gentle size reduction process with less abrasion.

The mill can be found in virtually all industries where the quality control process places the highest demands on purity, speed, fineness and reproducibility.

It is ideally suited for research applications or ultrafine colloidal grinding, as well as for routine tasks such as mixing and homogenizing soft, hard, brittle or fibrous materials.

行星式球磨儀 PM 100 CMWET GRINDING WITH THE PM 100 CM

Wet grinding is used to obtain particle sizes below 5 μm, as small particles tend to get charged on their surfaces and agglomerate, which makes further grinding in dry mode difficult. By adding a liquid or dispersant the particles can be kept separated.

To produce very fine particles below 1 micron by wet grinding, friction rather than impact is required. This is achieved by using a large number of small grinding balls which have a large surface and many friction points. The ideal filling level of the grinding jar should consist of 60 % small grinding balls.

The graphic shows the result of grinding zeolite microparticles at 600 rpm in the PM 100 CM. After 1.5 h of pulverization in isopropyl alcohol with 0.5 mm grinding balls, the D90 value of the original sample was reduced from 25 μm to 350 nm.

行星式球磨儀 PM 100 CM"COMFORT" GRINDING JARS FOR EXCELLENT RESULTS

The performance and the result of sample preparation are also determined by the choice of the grinding jar and its ball charge. The comfort range of grinding jars has been specially designed for extreme working conditions such as long-term trials, wet grinding, high mechanical loads and maximum speeds as well as for mechanical alloying.

Available jar sizes: 12 ml / 25 ml / 50 ml / 80 ml / 125 ml / 250 ml / 500 ml
Pressure-tight and dust-proof O-ring sealing prevents material spillage, even after clamping is released
Jars and balls available in 7 materials: hardened steel, stainless steel, tungsten carbide, agate, sintered aluminium oxide, silicon nitride, zirconium oxide
Stainless steel protective jacket for agate, sintered aluminum oxide, zirconium oxide and tungsten carbide grinding jars
A groove between jar body and lid allows for easy opening of the lid, e. g. with the help of a spatula, if there are underpressure effects inside the jar

JARS & LIDS FOR SPECIAL APPLICATIONS

For colloidal or wet grinding, the use of a grinding jar with a special closure device is recommended
Aeration lids are designed for working under inert atmosphere, for example if oxygen can influence the grinding process or the mechanosynthesis. The lids allow the introduction of gases like argon or nitrogen into the grinding jar.
Optional pressure and temperature measuring system PM GrindControl

行星式球磨儀 PM 100 CMRECOMMENDED JAR FILLINGS

To produce optimum grinding results, the jar size should be adapted to the sample amount to be processed. The grinding balls are ideally sized 3 times bigger than the largest sample piece. Following this rule of thumb, the number of grinding balls for each ball size and jar volume is indicated in the table below. To pulverize, for example, 200 ml of a sample consisting of 7 mm particles, a 500 ml jar and grinding balls sized at least 20 mm or larger are recommended. According to the table, 25 grinding balls are required.

The table shows the recommended charges (in pieces) of differently sized grinding balls in relation to the grinding jar volume, sample amount and maximum feed size.

受樣品材料性質和儀器配置/設定的影響

行星式球磨儀 PM 100 CM

作用原理

行星式球磨儀的研磨罐位于底部太陽輪的偏心位置。研磨罐繞軸自轉，與公共的太陽輪轉動方向正好想法，太陽輪與研磨罐的轉速比為1：-1。研磨罐中的球在于研磨罐一起運動時受到Coriolis力（即自轉偏向力）的疊加影響。研磨罐和研磨球的運動速度之差產生強摩擦力和撞擊力，因而釋放了大量的動能。這種撞擊和摩擦的組合使得行星式球磨儀研磨時的粉碎度及高。為了保持運動時的平衡，擁有一個研磨工位的行星式球磨儀需要配重。PM100CM型行星式球磨儀的配重可在一條傾斜的導軌上調整。不同大小的研磨罐的不同重心高度由此得到精確的補償，從而避免了儀器運行時的晃動和振蕩。剩余的振動可以通過儀器底座的微小自由運動（底座自由力補償）得到補償。這種新型的FFCS技術基于d’Alembert原理，允許機身作很小的回旋運動，自動完成質量補償。實驗桌面只受到儀器底座產生的微小摩擦力。 PM100CM型行星式球磨儀運行時安靜、安全，即使在罐內振動達到最大時仍能保證最優的振動補償，因此可置于實驗室桌面，無需監護。
